BlackRock Bitumen supplies Australian Standards bitumen worldwide, delivering consistent quality for global road construction projects.
It is viscosity-graded bitumen manufactured and tested according to Australian Standards for consistent road performance.
Australian Standards bitumen is graded by viscosity at specific temperatures, not by penetration like some international standards.
Higher-viscosity grades such as C320, C450, and C600 perform better in hot conditions.
It is widely used in road construction, spray sealing, highways, and heavy-traffic pavements.
AS bitumen focuses on viscosity and temperature performance, offering better consistency across varying climates.
Selection depends on traffic load, climate conditions, pavement design, and project specifications.
